A potentiometer being calibrated and then measuring an unknown voltage. R 1 is the resistance of the entire resistance wire. The arrow head represents the moving wiper.. In this circuit, the ends of a uniform resistance wire R 1 are connected to a regulated DC supply V S for use as a voltage divider.
Linear taper potentiometers [4] are used when the division ratio of the potentiometer must be proportional to the angle of shaft rotation (or slider position), for example, controls used for adjusting the centering of the display on an analog cathode-ray oscilloscope. Precision potentiometers have an accurate relationship between resistance and ...
The skeleton potentiometer works like a regular circular potentiometer, but is stripped of its enclosure, shaft, and fixings. The full movement of a skeleton potentiometer is less than a single turn. The other type is the multi-turn potentiometer which moves the slider along the resistive track via a gearing arrangement. The gearing is such ...
A diagram showing the wiring of a Gibson Les Paul electric guitar. Shown are the humbucker pickups with individual tone and volume controls (T and V, respectively), 3-way pickup selector switch, tone capacitors that form a passive low-pass filter, the output jack and connections between those components.
While quite similar to normal potentiometers, digital potentiometers are constrained by current limit in the range of tens of milliamperes. Also, most digital potentiometers limit the voltage range on the two input terminals (of the resistor) to the digital supply range (e.g. 0–5 VDC), so additional circuitry may be required to replace a conventional potentiometer, (although digital ...

Since the measuring cable may sag or be deflected by wind or gravity, the overall precision of a string potentiometer measurement is limited. The cable mechanism limits the speed at which the measured object can move. Changing temperatures affect both the length of the cable and the resistance value of the potentiometer.
Motorized potentiometers are used in industrial controls. [1] Motorized potentiometers may be used for remote control applications. [3] Motorized potentiometers can be used to build electrical/electronic analog computers. The motorized potentiometer can act as a computing element, but also as a way to convert a physical into an electrical value.
